Ecuador's Power Grid Outlook Improves Heading Into Rainy Season

For the first time in over a year, Ecuador's electricity situation looks cautiously positive — but the grid remains fragile.

The Good News

After a brutal stretch of rolling blackouts throughout 2024 and into early 2025 that cut power for up to 14 hours per day in some areas, several factors have aligned to improve the outlook:

• Heavy rains during the current rainy season (roughly December through May) have refilled most major hydroelectric reservoirs. Ecuador generates approximately 80% of its electricity from hydropower, making rainfall the single most important variable in the country's energy equation
• Mazar reservoir — the country's largest hydroelectric storage facility, located in Azuay province — has hit maximum capacity. Mazar feeds into the Paute hydroelectric complex, which provides a significant share of national electricity
• A new 200 MW thermal power plant has come online, adding backup capacity that does not depend on rainfall
• Three Turkish floating power barges remain stationed at Ecuadorian ports as emergency backup generators, available to feed electricity into the grid if hydroelectric output drops

Why the Blackouts Happened

The 2024-2025 blackout crisis was triggered by a combination of factors:

• Severe drought — an El Nino-driven dry season dramatically reduced water levels in the reservoirs that feed Ecuador's hydroelectric dams
• Decades of underinvestment in the power grid, including failure to diversify beyond hydropower
• Coca Codo Sinclair problems — Ecuador's largest hydroelectric plant (1,500 MW capacity, roughly one-third of national capacity), built by Chinese firm Sinohydro during the Correa administration, has been plagued by structural defects, sedimentation from river erosion, and reduced output
• Growing electricity demand from population growth, urbanization, and the expansion of energy-intensive industries like mining

The result was months of scheduled and unscheduled blackouts that disrupted businesses, damaged equipment, and forced millions of Ecuadorians to adjust their daily lives around power outage schedules.

The Remaining Risks

The improved outlook comes with significant caveats:

• Coca Codo Sinclair continues to face erosion of the Coca River upstream of the dam, which threatens the plant's water intake infrastructure. If erosion worsens, the plant could lose capacity at any time. Coca Codo Sinclair represents roughly one-third of Ecuador's total generating capacity — losing it would be catastrophic
• The rainy season will end. Ecuador's improved reservoir levels are a function of current rainfall. When the dry season begins (roughly June-November), the same vulnerability that caused the 2024 crisis will return unless structural changes are made
• Mid-March warning sign — Ecuador's national electricity operator (CENACE) ordered businesses to activate self-generation systems (backup generators) as a precautionary measure, suggesting that grid margins remain thin even with improved conditions
• Transmission infrastructure is aging and insufficient. Even when generation capacity is adequate, the grid's ability to deliver power from dams in the highlands to demand centers on the coast has limits

What This Means for Expats

• The blackout risk is lower than it has been in over a year, but it has not been eliminated. If you experienced the 2024 blackouts, you know the disruption they cause. Do not discard your backup plans yet
• If you own a backup generator, keep it maintained and fueled. The CENACE order to businesses to activate self-generation systems suggests the grid operator is not fully confident in supply margins
• UPS (uninterruptible power supply) units remain a smart investment for computers, routers, and medical equipment. A quality UPS costs $100-300 and provides 15-60 minutes of backup power — enough to save work and safely shut down equipment
• Watch the dry season forecast. If meteorologists predict a below-average rainy season or an early onset of dry conditions, electricity rationing could return as early as mid-2026
• If you run a business in Ecuador, the CENACE self-generation order is a signal to take seriously. Having backup power capability is not optional for businesses that cannot afford downtime
• The fundamental problem — overdependence on hydropower — has not been solved. Ecuador needs thermal, solar, and wind capacity to reduce its vulnerability to drought. Until that diversification happens, the country remains one dry season away from another crisis
